The CHEMetrics test kits for the determination of Hydrogen Peroxide in aqueous solutions are based on patented Self-Filling Reagent Ampoule technology, and employ the Ferric Thiocyanate, DPD and Ceric Sulphate methods, delivering sensitivity and accuracy within two minutes or less. Premixed. Premeasured. Precise. Each kit contains 30 tests. Suitable for food and beverage industry applications as well as industrial effluent testing.

The Ferric Thiocyanate Method

The ferric thiocyanate method consists of ammonium thiocyanate and ferrous iron in an acidic solution. Hydrogen peroxide oxidises ferrous to ferric iron, resulting in the formation of a red thiocyanate complex. Chlorine does not interfere with this method, but Ferric iron does. Results are expressed as ppm (mg/l) H2O2.

The DPD Method

With the DPD Method, hydrogen peroxide in the sample reacts with DPD (N, N-diethyl-p-phenylenediamine) in the presence of potassium iodide and ammonium molybdate to form a pink color in the ampoule. Results are expressed as ppm (mg/l) H2O2.

The Ceric Sulphate Titrimetric Method

CHEMetrics has developed a patented reverse titrimetric method using ceric sulphate as the titrant and ferroin as the end point indicator. A color change from green to orange signals the end of the titration. Results are expressed as percent (%) H2O2. The test range can be also be modified by performing a sample dilution. Details are provided in the kit instructions for testing samples in the ranges of 0.01 - 0.1% through 2- 20%.

* Up to 20% with dilution

Developed by CHEMetrics, Inc.


Hydrogen peroxide is a strong oxidising agent with a wide variety of uses. Applications include the treating of industrial effluents and domestic waste and serving as a disinfectant in aseptic packaging. For the food and beverage industry, CHEMetrics Hydrogen Peroxide CHEMets® and Vacu-vials® products are used extensively to monitor sterilisation solution residuals in Extended Shelf Life (ESL) and aseptic packaging applications. The product cartons are sprayed with hydrogen peroxide to pre-sterilise them, and then heated or pressed to remove the hydrogen peroxide. A hydrogen peroxide solution is also used to clean and sterilise manufacturing equipment used in the aseptic packaging processing line.
